Output lookup fields in serialiser for OneToOne relationship
I'd like to output in my API fields coming from two different (related) models. I have this models.py: class User(AbstractBaseUser): first_name = models.CharField(max_length=30, blank=True, null=True) surname = models.CharField(max_length=30, blank=True, null=True) def __str__(self): return "%s %s" % (self.first_name, self.surname) # I don't want to change this. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='profile', null=True, blank=True) first_nameUnregistered = models.CharField(max_length=120, null=True, blank=True) surnameUnregistered = models.CharField(max_length=120, null=True, blank=True) This is my views.py: class ProfileSerialiser(serializers.HyperlinkedModelSerializer): user = serializers.StringRelatedField(many=False) class Meta: model = Profile fields = ('first_nameUnregistered', 'surnameUnregistered', 'user') And the serialiser: class ProfileViewSet(viewsets.ModelViewSet): queryset = Profile.objects.all() serializer_class = ProfileSerialiser Right now what I see when I go to my /api/profliles endpoint it: [ { "first_nameUnregistered": "", "surnameUnregistered": "", "user": "The full user name, coming from def __str__(self):" }, [...] I want to get something like: [ { "first_nameUnregistered": "", "surnameUnregistered": "", "user.first_name": "first name" "user.surnamee": "surname" }, [...] Lookups such as profile__user.first_name seem not to work, I cannot merge the two querysets because they're from different models, and I cannot use properties in the fields definition of the serialiser. How can I achieve what I want? -
Iterate over queryset in groups of a certain amount
Basically, I want to use a Bootstrap Carousel with a queryset. My question is as to how I should iterate over the queryset so that I can put three objects into a div and then the next three into another div and so on depending on the size of the queryset. See the preudocode below. {% for group in object_list/3 %} <div class=""> {% for object in group %} <p>{{object}}</p> {% endfor %} </div> {% endfor %} -

Errors while encoding the InMemoryUploadFile in to base64 encoded string in Django
I am trying to convert the image uploaded to the Django server to the base64 string. I have looked and tried various solutions mentioned on this site and other blogs. Finally I found the accepted answer here on stack-overflow - Encode Base64 Django ImageField Stream I tried - image = request.data.get("image", None) b64_img = base64.b64encode(image.file.read()) However this is throwing error - TypeError: must be str, not bytes Can anyone here help me out in figuring out how to actually convert InMemoryUploadedFile to the encoded base64 string?

Making models.py for Django Rest Framework Primary key and foreign key

Why is React/TypeScript/axios ignoring my session cookies?
Good day, fine Stack Overflow citizens. I have a Django back end serving a React front end. React uses axios to perform requests and handle CSRF magic (which Django employs out of the box). I had a fun time reacquainting myself with the ins and outs of CSRF and CORS, and finally managed to get things running with Django (using Django REST Framework) serving on http://localhost:8000 and React on http://localhost:3000. I especially love how you can set the following and dust your hands off from otherwise tiring details: axios.defaults.xsrfCookieName = XSRF_COOKIE_NAME; axios.defaults.xsrfHeaderName = XSRF_HEADER_NAME; axios.defaults.withCredentials = true; However, now that I've deployed this code into my production environment, Django complains when I try to log in (with the message CSRF verification failed. Request aborted). After some digging, I found this to be because even though Django sends Set-Cookie headers with the CSRF token, it isn't being set in my browser. I have the following headers in my client request: Host: backend.example.com User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:75.0) Gecko/20100101 Firefox/75.0 Accept: application/json, text/plain, */* Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate, br Origin: https://frontend.example.com Connection: keep-alive Referer: https://frontend.example.com/login And this is the server response: HTTP/1.1 200 OK Connection: keep-alive Server: … -
How to join a table that is not subject to a foreign key constraint to an outer join

Is there a library for emoji tooltip in Django?
So I'm a newbie in Django, and wondering if there is a library that has emoji tooltip. (I'm not even sure you call it 'tooltip') The best example I think is the one that Notion has. As you may know, you can freely use emoji (may be from getemoji.com?) in Notion. What I eventually want is to let user select appropriate emoji that best expresses his/her feeling in diary app. I have no idea on how it works and would very much appreciate your advice.

How to render something in React only if a link has been clicked?
I am learning how to use Django and React together, and I state that I don't know if what I am trying to do is best practise (if not, please let me know what is the best way to achieve this, as I am quite sure this is a design pattern). So I have managed to render some data in the frontend by fetching it from my backend API (built with Django Rest Framework). What I would like to do is to render a list of objects only if the user clicks on a tag. How can I achieve that? Obviously I don't want to redirect to 'api/....' but rather redirect the user on the same page, which based on that link being clicked should display the list. Just to make it clear here is a screenshot: When I click on the 'Your Assessments' link I would like the list (in this case 'Test1', 'Test2', 'Test3') to be displayed. How can I implement this? Is a link the better choice for what I want to achieve or should I rather use a button and watch for an 'onClick' event? Or do I have to write Django views into 'frontent/views.py'? Here … -
sharing a (django-channels 1.x) channel_session variable between 2 users?
I wrote a lot of code with the assumption that a channel_session variable defined inside of a Group would be shared by all the users inside of that Group. I was wrong -- it is only defined for the one user. I need both users in a Group to be able to access one class instance. I am using attrs+cattrs for serialization so that is not a problem. I am storing this class instance in the channel_session variable. This class instance contains the game state (the app is a game): creator/opponent x,y history, current direction, etc. It's a very simple game. Tron lightcycles, but to move, the user must answer a math problem. Please help. Thanks. -
Django PayPal and dynamic price
I'm using Django PayPal for subscriptions for users in my app which also has coupons. Coupons are created by the admin, with coupon code, and discount value which gets calculated and results a total price. And I was wondering, since im new to PayPal with django - how can I change the price dynamically depending on the users coupon validation? I'm using jQuery to change the price depending on the coupon, and the price changes in the html page, but not on the server side. The price gets loaded at the same time as html page where the coupon input is, and where the PayPal form is, so PayPal dict takes the default price the moment page gets loaded, which I don't wont. As I said, regarding the front end, price gets changed on click(to apply button), but I can't send the data back to the server, since the request already passed because. This is my jQuery and coupons fetching code: views.py def get_coupon(request): if request.is_ajax(): try: plan = Subscription.objects.get(pk=request.session.get('plan_id')) coupon = Coupon.objects.get(code__iexact=request.GET.get('coupon', None)) discount = coupon.discount total = plan.sum_price - (plan.sum_price * discount / 100) data = { 'total': total, 'discount': discount, 'coupon': coupon.code } return JsonResponse(data, safe=False) except … -
